If your HP laptop is plugged in but not charging, several factors could be at play. It might be due to a faulty AC adapter, damaged charging port, or battery issues. Check the power outlet and ensure the adapter is securely connected. Examine the charging wire for any indications of impairment. Verify if the charging port on the laptop is clean and free from debris. Additionally, outdated BIOS or driver issues could also contribute to this problem. Troubleshoot by updating BIOS and drivers, performing a power cycle, or testing with a different adapter. For additional help, get in touch with HP support if issues continue.
